X Minus One


X Minus One aired on NBC from 24 April 55 until 9 January 58 for a total of 124 episodes with one pilot or audition story. There was a revival of the series in 1973 when radio was attempting to bring back radio drama and it lasted until 1975. The show occupied numerous time slots through out its run in the 50's and thus was never able to generate a large following.

X Minus One was an extension of Dimension X which aired on NBC from 1950-51. The first fifteen scripts used for X Minus One were scripts used in the airing of Dimension X; however, it soon found its own little niche. The stories for the show came from two of the most popular science fiction magazines at the time; Astounding and Galaxy. Adaptations of these stories were performed by Ernest Kinoy and George Lefferts. They even wrote a few original stories of their own. The writers of the magazine stories were not well known then but now are the giants of today. These stories came from the minds of Ray Bradbury, Isaac Asimov, and Poul Anderson to name a few.

This series has survived from its original airing in high quality to be enjoyed today.

NOTE: Updated Release! Several misdated shows replaced with correct copies and other miscellaneous changes (08-Mar-2011).

I used to listen to this when I was in high school back in the '80s. A local public radio station would play it and some other classics late at night. These are excellent dramatizations of some classic science fiction stories. Just can't get enough of this good stuff!

When you right click on the link, a box comes up. One of the items in the box is "download file" or words to that effect. Click on that.

Sci Fi and radio are a perfect match, and X Minus one did it beautifully.

I can't believe I'm this dense. I'm quite computer savvy, but cannot figure out how to download anything here. Right click does not show a 'save to target' function.

What's the secret?

I can't believe this isn't 5 stars. There is no better OTR series. Listen to Cave of Night, and then remember this was aired before Sputnik!

I have enjoyed the complete series along with Dimension X and other cbs series. This is a great plan for us that remember communication before times. It is amazing to realize that the authors', of Galaxy magazines and other sci fi magazines before Asimov magazines, stories are found here. I am 50 decades young and even though I have in my mental file cabinets the correct answers I am just happy to list what I remember at this time. I love sci fi and sci fact. I to expected space travel to be more advanced. We have cell phones, online chat, I see u and u can see me. but the medical tech, agricultural tech, and meteorology tech is not where those writers saw us including Roddenberry. But I am glad to be apart of the beginnings. And God willing maybe more.

Your archive is terrific! When I was in my teens I listened to as many episodes as I could. Now, as an old man in my 70s, I can enjoy all the episodes any time I wish to hear them.Thanks for a great site!

Really pathetic that someone gave a 1-star rating to this excellent series because he or she was too incompetent to figure out how to download it while hundreds of other people have downloaded it with no problem

Hello I'm 31 and live in Canada. I just wanted to say thanks for making these radio play's available I used to stay up really late hoping they would play these on my local station, sometimes they would and those were some great night but the stopped the show some time ago. The people who made these put there heart and soul into these stories and I'm happy to see the younger audience is still interested. You have a wonderful site, thank you :)

"Appointment In Tomorrow"

Jan Trageron - truly Machiavellian bureaucrat; right up there with O'Brien in 1984... scarier than any alien.
classic quotes:
"i like being fat, it makes our relationship more poignant"
"the average man is exactly where he was ten years ago when we took over - except he's got a new god."
"get a hold of yourself and stop taking fantasy in the veins"
"i said shut up"

oligarchy at it's finest. right down to his manipulation of those rebels who think they're hunting him.

- just really damn good.

One of the all-time great science-fiction shows, and we're lucky that all the episodes survive intact and in such great quality! I can listen to these stories over and over again....

X Minus One is hands down one of the best sci fi radio series ever. The quality of these recordings are fair to excellent, and includes a variety of stories ranging from Martian Ray Guns to bizarre tales of the strange and macabre. This is a must have for any collector, and definitely a good place to start for the uninitiated.
